BRUCE JOHN DICKINSON, OF AMBRIIDGE, PENNSYLVANIA.

HOSE-COUPLING.

To all whom it may concern Be it known that I, BRUCE JOHN DICKIN- SON, acitizen of the United States of America, residing at Ambridge, in thecounty of Beaver and State of Pennsylvania, have invented certain newand useful Improvements in Hose-Couplers, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to hose couplers, and the primary object of myinvention is the provision of positive and reliable means, in a manneras will be hereinafter set forth, for easily and quickly connecting theconfronting ends of two sections of hose or a section of hose to a fireplug or hydrant.

Another object of this invention is to provide a hose coupler thatobviates the necessity of using a wrench or resorting to the use ofscrew threads for obtaining a nonleakable connection between hose orother fluid conduits.

A further object of this invention is to provide a hose coupler that isinexpensive to manufacture, not liable to injury by ordinary use, andhighly efficient for the purposes for which it is intended.

WVith the above and other objects in view the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein t Figure 1 is a planof the hose coupler partly broken away. Fig. 2 is a longitudinalsectional view of the same. Fig. 3 is an end view of the coupler partlybroken away and partly in section. Fig. 4 is a perspective view of adetached locking member adapted to form part of the coupler. Fig. 5 is aplan of one of the coupling members. Figs. 6, 7 and 8 are detail viewsof one of the locking members, and Fig. 9 is a perspective view of adetached spring.

A coupler in accordance with this invention comprises members 1 and 2having tapering ends with the outer end of said members recessed, as at3 and the walls of said recesses scolloped, corrugated or provided withirregular surfaces 4: to frictionally hold the ends of sections of hose5. The ends of the hose 5 engage the inner ends of the recesses 3 andare forced into engagement with the walls of said recesses by expansiblebands 6, preferably made of copper where- Specification of LettersPatent.

by the bands can be hammered or otherwise expanded to force the materialof the hose into the corrugated or irregular walls of the recesses 3.This is accomplished in a man ner that counter-sinks the bands 6 andprovides a smooth bore from one hose section to the other.

The member 2 has the inner end thereof provided with an annular exteriorseat 7 for a coupling member 8 that is movably held relatively to themember 2 by anti-frictional balls 9. These balls engage in an annularrace 10 provided therefor in the member 2 and in an annular race 11formed in the coupling member 8, the race 11 confronting the race 10 toreceive the balls 9. The antifrictional balls are placed within theraces through the medium of an opening 12 in the member 8, said openingbeing normally closed by a plug 13.

The member 8 is provided with inclined equally spaced openings 14rectangular in plan and these openings receive locking members 15 havingbeveled teeth 16 to engage in annular grooves 17 provided therefor inthe reduced inner end of the member 1, said member being reduced toprovide an annular seat 18 for the end of the coupling member 8.

The locking members 15 are retained within the openings 14 by flatsprings 19 countersunk within the outer surface of the member 8 andretained therein by set screws 20. The outer ends of the locking membersare cut away, as at 21 to receive the free ends of the springs 19.

The screws 20 retain a yieldable band 22 upon the member 8 with the endsof the band extending on to the members 1 and 2. This band is preferablymade of rubber and is employed to prevent the springs 19 fromcryst-allizing or deteriorating due to the forces of nature, moistureand rough usage to which the coupler is subjected.

Interposed between the confronting ends of the members 1 and 2 is aresilient gasket 28, preferably made of rubber, said gasket insuring anon-leakable connection between the members 1 and 2.

In practice, it is only necessary to spring the coupling member 8 intoengagement with the member 1 and to make sure of the locking members 15engaging the member 1, a slight rotation of the member 2 relatively tothe member 1 firmly seats said coupling member with the teeth 16 thereofengaging in the grooves 17. pling member are protected as they projectinwardly from the coupling member 8 and cannot be injured When the endof the hose ,is dragged or rapidly moved over a street or rough surface.The member 8 can be freely revolved relatively to the member 2 and theparts of the member 2 can be easily assembled. Irrespective of theposition of the member 2 relatively to the member 1 the end of thecoupling member 8 can be sprung into engagement with the reduced end ofthe member 1. The coupling member 8 has 0ppositely disposed pins 2&projecting through the rubber band or sleeve 22 to facilitate movingsaid coupling member to firmly seat the locking members. The member 1has pins 24 to facilitate moving said member.

The coupler members can be made of light and durable material, as brassand the cou- The teeth 16 of the cou pler in its entirety can be made ofvarious sizes.

What I claim is A hose coupler comprising members adapted to have theends of sections of hose connected thereto, a coupling member revolublymounted upon one of the first mentioned members, spring pressed lockingmembers equally spaced in said coupling member and adapted to engage inthe reduced end of the other first mentioned inenr her, and a yieldableband carried by said coupling member and extending on to the firstmentioned members.

In testimony whereof I aflix my signature in the presence of tWoWitnesses.
